Although the drinking of hydrogen-gas-infused water can help treat rheumatoid arthritis, the effects are limited. Scientists have developed what could be a better alternative, though, in the form of tiny injectable gas-emitting “micromotors.”Continue R… Continue reading “Micromotors” could more effectively treat rheumatoid arthritis

Disco balls take a zillion mirrors glued to a sphere and shine a spotlight on them. But what if the ball itself was the light source? Here’s a modern version that uses addressable LEDs in a 3D-printed sphere that also hides the electronics inside the ball itself.
Check out the video below to see the fantastic results. It’s a Teensy 3.6 driving a whopping 130 WS2812 LEDs to make this happen. (The sphere has the highest surface area to volume ratio!) There’s even a microphone and an accelerometer to make the orb interactive. Hidden inside is a 4400 mAh battery …read more

Every person who reads these pages is likely to have encountered a neodymium magnet. Most of us interact with them on a daily basis, so it is easy to assume that the process for their manufacture must be simple since they are everywhere. That is not the case, and there is value in knowing how the magnets are manufactured so that the next time you pick one up or put a reminder on the fridge you can appreciate the labor that goes into one.
[Michael Brand] writes the Super Magnet Man blog and he walks us through the high-level steps …read more
